Specification of Letters Patent Application filed'January 13, 1821. Serial No. 436,952.

T 0 all whom it may concern:

Be it known that I, Gnoncn .l/VILBER ara's, a citizen of the United States, and a resident of Hot'Springs, in the county of Garland and State of Arkansas, have invented certain new and useful Improvements which is of simple and durable construction," reliable 1n operatlon an'd easy and inexpen sive to manufacture, which is highly efficient in use in that it conveys the steam from the generating chamber to the container for the substance being cooked without exposing the steam to the possibility or danger of be- ,ing condensed and which delivers the steam to the bottom of the container whereby the steam rises upwardly through the substance to thereby not only cook but also to enhance the delectable qualities of the substance and which provides for the ready association and disassociation of the elements of the cooker.

Other objects and advantages of the in-' vention reside in certain novel features of construction, combination and arrangement of par'ts which will be hereinafter more fully described andparticularly pointedout in the appended claims, reference bcing had ofthis specification, and in which:

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment .of the invention, the outer boiler or vessel is designated at 10 and is constructed of any suitable material, prefen ably metal. The vessel is preferably of cylindrical construction having an integral to the accompanying drawings forming part imperforate bottom 11 andhaving its upper end open and the material of the vessel around the marginal open end spun or rounded, as shown at12 in Fig. 2., Suitable handles 14lare provided on the outer boiler. An inner boiler or container 15 is provided,

and is also preferably constructed of metal.

Theinner boiler is of substantially cylindrical construction and has an integral impen forate bottom 16 and .its upper open end rolled, as at 17, to accommodate a cover 18 having a curved marginal flange 19 coop erable with the rolled marginal edge 17 to retain the cover ill'ClOSGd snug fitting relation on the inner container. l

"The. innercontainer is arranged in the outer vessel and is supported in position thereinby means of an annular laterally extending flange 20 secured to the outer wall of the inner container adjacent the upper end thereof and adapted .to rest upon the rolled end '12 of'theouter vessel to support the innercontainer in position and to close the open end of the outer vessel. Interlock.- ing means is provided for retaining the outer vessel or boiler and container in proper relation and preferably consists of angle brackets 21 secured to the inner wall "of the outervessel and angle bracket 22 secured to the outerwall of the inner vessel and adapted to engage under theangle brackets 21 to interlock the vesseland to retain them in proper relation. Itis obviousthat in as-" sembling the vessel, the inner container 15 1s insertedwith n the outer vessel with the angle brackets22- out of alinemcnt or spaced horizontally from the angle'brackcts 21and after the container 15 has been fully inserted in'the outer vessel it is then rotated until its angle brackets 22 underlie the brackets 21 and effect the interlocking action;

The inner container, as shown clearly: in Fig. 2, terminates a substantial distance from' the bottom of the outer vessel 10 and the space between the bottom of these vessels constitutes a water chamber designated at 23.' Preferably'the water level is below the bottom 16' of the'container. The spaceabove the water level and the space dcfinedbetween theside walls or cylindrical walls of the outer and inner vessels constitute a steam 7 chamber which is designated at 24: into which the steam generated from the water 23 rises.

The inner vessel 15 is provided with steam ET container.

preferably comprises a steam conductor hav-.

ing the general form of a T-connection and including horizontal pipes 27 terminating at their ends in downwardly extending sleeves 28 adapted to embrace the upwardly extending portionof the elbows to thereby support the steam conductor and to connect it with the steam inlets. The horizontal pipes 27 communicate at their inner ends and cen-. trally of the container 15 with the vertical depending pipe 29 which extends from the horizontal pipes downwardly throu h the container to a point adjacent the ottom thereof. The steam conductor thus receives the steam from the steam chamber 24 and delivers it to the lower end of the'container 15 without exposing it to the liability of condensing and without in .anywise impairing the steam. From the lower end or delivery end of the pipe 29 the steam is discharged in all directions and then rises upwardly through the container.

In practice, the outer vessel or boiler 10is first filled with water to ,ap roximately the level shown in Fig 2. Siibstance to be cooked is placed in the container 15, the steam conductor having been first arranged therein. This container is then lifted by the flange 20 or by handles 30 and inserted in the outer vessel or boiler in the manner hereinabove described and is locked in this position by means of the angle brackets 21 and 22. The annular fiange20 then serves not only to support the inner container in place but also serves to seal the'steam chamber 24.

The cover 18 is then placed on the inner cona let ports communicating with said steam space, an annular flange fixedto the outer wall of said container and engaging the top of said outer boiler to seal the steam space and to support said inner boiler, interlocking means for maintaining said boilers in assembled relation including coacting angle brackets, elbows arranged in said inner container and communicating with said steam ports, and means for conducting said steam from said elbows to the lower end of said container comprising horizontal pipes .hav-

ing sleeves embracing sald elbows and a.

vertical depending pipe communicating with said horizontal pipes and having its delivery support said inner boiler, elbows arranged zontal pipes having sleeves embracing said elbows and a vertical depending pipe come municating with said horizontal pipes and having its delivery end disposed adjacent.

the bottom of said container.

3. A steam cooker comprising an outer boiler adapted to contain water, a. container arranged within said outer boiler and definports communicating with said steam" space,

. means for supporting said container on'said ing therewith a steam space and having inlet outer boiler and for sealing the steam space,

embracingsaid elbows and a vertical de pendlng plpe communlcating with said hori zontal pipes and having its delivery end dis-w posed adjacent the bottom of said container. 4. A steam co0ker of the character described comprising an-outer boiler, a.con tainer arranged in said outer boiler and defining therewith a steam space, an imperfo rate annular flange carried by the outer wall of said container and engaging thetop of said outer boiler to support the container and seal the steam space, interlocking means carried by the container and the outer boiler for maintaining the container and the boiler assembled, and means for conducting steam from the steamspace into said container.
